So when this bug was first reported we were using multipath 0.4.8, it doesn't appear to have this cookie mechanism. 0.4.9 does (oneiric and higher); I have been unable to reproduce the issue with 0.4.9. Going back through the logs...
""" >From 8d63b33d0996e141a2451df552b062b908db15bc Mon Sep 17 00:00:00 2001 From: Benjamin Marzinski <bmarz...@redhat.com> Date: Mon, 17 May 2010 14:03:38 -0500 Subject: [PATCH] multipath: add udev sync support. device-mapper in now able to synchronize operations through udev. This patch allows multipath and kpartx to make use of this feature. If kpartx is run with "-s", it waits for the partitions to be created before returning. Multipath will now always wait for the devices to be created before returning. This feature requires dm_task_set_cookie() which was finalized in device-mapper version 1.2.38 """ Appears to be where cookie support was initially added. I'll retest with 0.4.8 to verify that the fault still exists (probably) and take it from there. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/585027 Title: Race condition with dmsetup causes 'map already present' messages To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/multipath-tools/+bug/585027/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
